Rapid advances in technology and consumer demand for high-quality cars are drive the development of the automotive industry. To ensure that each vehicle meets the highest standards in the design and production process, DV (Design Verification, Design Verification) and PV (Production Validation, Production Verification) technology play a vital role. These two technologies not only ensure the performance, safety and reliability of the car, but also provide a better driving experience for consumers.
一、 What is a DV and a PV?
1、 DV (Design-Verification) Testing is a design verification test: the purpose is to verify whether the pr
2、oduct design meets the specified requirements, and to find out the defects and deficiencies in the design, to provide a basis for the improvement of the product.
3、 PV (Production-Validation) Testing is a production validation test: the purpose is to verify that the mass production process and tooling production products meet the requirements and find out the problems and improvement measures in the production process.
DV test is the physical test of pre-produced or produced parts; PV test is the physical test of mass-produced parts.
二、Test items
三、Test process
Both DV tests and PV tests are performed in the following procedures:
四、Difference and connection between the two
1. distinguish
2. Association and binding
DV test and PV test are two important links in the product development process, which are interrelated and inseparable. DV test lays the foundation for PV test, and PV test is the further verification and perfection of DV test.
lThe results of DV test provide an important basis for PV test. PV test can find the missing problems and deficiencies in DV test, and provide a direction for the improvement of DV test.
lThe combination of DV test and PV test can effectively improve the quality and reliability of products, shorten the product development cycle, and reduce the product development cost.
五、Application in the automotive industry
lThe DV test can be used to verify the vibration performance, durability performance, reliability and so on of auto parts. For example, the vibration test of the car seat can verify whether the seat can withstand long vibration, and the durability test of the car tire can verify whether the tire can withstand enough wear
lThe PV test can be used to verify the production process capacity of the auto parts. For example, PV testing of automobile engine blocks can verify that the production process can stably produce blocks that meet the quality requirements.
The application of DV and PV technologies has played a crucial role in the automotive industry. Their continuous innovation and improvement have not only promoted the progress of automobiles, but also brought more excellent automobile products to consumers around the world.
